Antimicrobial Effects of Ethanolic and Nano Extract Produced by Bark of Salix Alba on Growth of Some Pathogenic Microbes

Abstract

In this study, the comparison between the effectiveness biological of alcoholic and nano extract used by green synthesis method of Salix alba( willows ) plant on the growth of two types of pathogenic microbes isolates which have been obtained from AL-alywia hospital for children thats Proteus vulgaris(Gram-ve) ,and yeast Candida albicanes(Gram +ve) . Alcoholic extract that gave the highest effect on growth of Proteus vulgaris bacteria by inhibition zone (8mm ), but not effected on the growth of the yeast Candida albicanes. While the nano extract has been shown that the highest effect on the growth of Proteus vulgaris bacteria by inhibition zone reached to (21mm), followed by Candida albicanes by inhibition zone reached to (11mm).
